Puget Sound Mill & Timber Company cut its first lumber at Port Angeles in 1914. Logging operations were located at Twin. The mill was out of business by 1927.

Twin is a small settlement on the Strait of Juan de Fuca 20 miles west of Port Angeles at the mouth of Twin River in north central Clallam County named for its position at the mouths of West Twin and East Twin rivers. It wasn't until the turn of the century when the Chicago, Milwaukee, St. Paul and Pacific Railroad was built between Twin and Port Angeles that the towns boomed. Puget Sound Mill and Timber established headquarters in Twin after the railroad came. With the railroad linking Twin to other communities, the town thrived, and so did business. The town received a boost during World War I when the government assigned 27,000 men to its "Spruce Division" to harvest spruce for the wing spars of the nations airplanes. About 200 of the soldier-loggers were stationed in Twin. This was Twin's high tide. At the time, Twin was the largest logging camp in the world, records show. With the extra lumber required by military production and the thriving timber industry, Twin was alive and booming. But the war, the industry boom and the good luck of Twin would all soon end--along with Twin itself. An influenza epidemic hit the logging community in 1918. The flu killed dozens of the community residents and left many others weakened. This epidemic was followed by the news of the end of World War I in 1919. The good news of the end of war brought bad economic times to Twin. The "Spruce Division" was disbanded and the 200 soldier-loggers left Twin. As Twin struggled to recover, nature intervened. The "big wind of '21" destroyed 8 million board feet of sellable lumber growing on the North Olympic Peninsula. While the 110 mph winds damaged the timber industry around the North Olympic Peninsula, the storm devastated Twin's logging industry. Twin's fate was sealed with the stock market crash of 1929. The Great Depression led the timber companies to cut back production and Twin was severely impacted. In the early 1930s, the Chicago, Milwaukee, St. Paul and Pacific Railroad took their rails back and tore up the tracks connecting Twin to the outside world.
